Title:
  When wireless is enabled, anything touching the network deadlocks in
  the kernel

Status in “network-manager” package in Ubuntu:
  Expired

Bug description:
  After the update today (2011/09/18), if I have by broadcom wireless
  enabled then, after a minute or so of uptime, anything which touches
  the network will get deadlocked in in the kernel, with rtnl_lock near
  the top of the kernel stack.  This includes everything from firefox
  and evolution, to "ip addr" and even "sudo", which obviously makes the
  system nearly unusable.  This also prevented "stop network-manager"
  from returning.

  This doesn't seem to be directly a kernel problem - the
  3.0.0-8-generic kernel was working fine up until today, and I've also
  tried the 3.0.0-7-generic kernel which also worked; the same issue
  occurs.

  Syslog attached.
